-To all whom it may concern I Be it known that I, CHARLES B. DoomN, a citizen of the United States, residing at .San Antonio, in the county of Bexar and State-of Texas, have invented certainnew and useful Improvements in Liquid Measures and Strainers; of which-the following is a specification.

This invention relates to'Idevices for measuring' and straining liquids and discharging them into a receptacle or tank without exposing the liquids after being strained to the atmosphere or rendering the liquid liable to be deteriorated by dust or other-foreign matter.. I

W'thhese and other objects in view, the

invention consists in certain novel features of construction, as hereinafter shown and described and then specifically pointed out 1n the claims; andin the drawings illustrative of the preferred embodiment of the invent1on- Figure 1 is a vertical-section of the im proved device. Fig. 2 isa transverse section onthe line 2-2 of Fig. 1.

Fig. 3 is a view similar to Fig. 1 illustrating a .modification in the construction.

The improved device comprises a measuring can represented as a whole at 10 and of any suitable size or capacity. The member 10 ispreferably formed with an outwardly flaring upper end 11- and provided with a suitable lifting handle 12 at one side. Lo-

.cated within the body 10 and spaced from its lower end is a downwardly directed conical diaphragmor partition 13 having a dis: charge opening at, its lowest point, from which a discharge conduit 14 leads laterally through one of the side walls of the receptacle as shown at 15. The conduit-14 exits free end.

'At its free end the hose member is providedwith adischarge nozzle 18-, preferably reduced at Attached 'to the side of the casing 10 is the hose member when in its upper; or inoperative position, as shown in Fi 1. The

'catch device 19 is preferably .0

resilient material and clasps'the hose with suflicient grip to hold it in place from displacement when not in use, but will readily yield when I Specification of Letters Patent. 1 Application filed April 1-1, 1917; Serial No. 162,171.

hose.

Surrounding the opening of the ing the seat 20 is a flat valve 21, of yieldab e sufiicient force isa'ppliedjo withdraw the p mberf 13 'is a valve seat represented at 20,r which is secured in any suitable manner "to the upper face of the diaphragm 13; Engagmaterial such as leather or hard rubber, and-extending vertically from the-valve is a lifting stem22. Connected to ,the' up per'face of the member 13 and spaced above the valve seat 20 'is a screen device represented as a whole at 23, and preferably formed-of suitable fabric material adapted to effectually screen oil or other liquids and extract therefrom particles offoreign matter. The screen material may be fine meshwire, or. other suitable filtering material,

depending upon the oil or other liquid which is to be screened. If gasolene is the liquid which is tobe measured, and screened,.the. material '23 maybe buck-skin or the like usually employed for screening gasolene'betfglre it is deposited the tanks of automo- A metal disk 24 is arranged centrally of the 'screen and to which the latter is attached, the member 24 being perforated to permit the stem 22 ,to slidably move therethrough. At its outer edge the screen member is provided with an annular frame or ring 25 to which the screen material is attached at its outer edge while the frame member 25 is riveted or otherwise secured to the member 13. An annular holding central disk24 to'still further secure and support the screen material. Bearingover the upper face of the screen material and its frame 25 is a bearing 27 having a central perforation through which the stem '22 passes. A supporting bracket 28 is connected at its ends to themember 27 and is perforated at its center to permit the stem 22 to pass through.

A spring 29 is loca' v 21 and the plate 24 to hold the valve 21- yieldabl in position upon its seat 20. Attac ed to the inner face of the receptacle 10 near its upper end is abracket 30 to which a bell-crank lever member 31 is pivoted at 32. ,Themember31 is coupled member 26 is applied to the under-face of the screen material where it engages the ted between the valve at its inner end to the stem 22 by a rod, 33.

At. its outer end the member 31 terminates in an enlargement 34 to receive the. thumb of the operator when he grasps the handle 12 by the fingers of one hand. The receptacle 10 above the diaphragm 13 will preferably be provided with annular beads 35 gaged to indicate the quarts, pints, gallons or other measures.

In Fig. 3 a modification in the construc tion is shown, consisting in forming the outlet 14L shorter than shown in Fig. 1 and forming a relatively large opening 36 in the side of the shell 10 below the diaphragm 13 to enable the hose 17 to be attached, the hose connection being disposed entirely within the shell 10. In the modified structure a hood or smaller shell 37 is disposed within the larger shell and attached by its lower edge to the diaphragm 13 and inclosing the valve 21. The hood 37 is provided with a plurality of relatively large-openings 38 in its lower portion and provided with a detachable cap 39 at its upper end, the latter provided with an aperture through which the stem 22 extends. The screen 23 is centrally apertured to receive the hood 37. The spring 29 operates at its upper end against the lower face of the cap 39. A supporting ring or flange 40 encircles the hood 37 and is attached thereto and operates to support the screen material, the ring 40 thus serving the same purpose as the'ring 26 in the structure shown in Fig. 1.

It will be obvious that with a device constructed as shown when a certain predetermined quantity of liquid is required, for instance, oil to be furnished to the oil reservoir of an automobile, the desired quantity is run into the receptacle 10 and the nozzle 18 connected into the receiving aperture of the reservoir or other receiver and heldin position with one hand while the receptacle is engaged by the handle 12 with the other hand. The operator then presses downwardly upon the terminal 34: of the operating bell-crank with the result of releasing the valve 21 and permitting the contents of the receptacle to flow through the hose into the reservoir or other receiver, the oil or other liquid being strained by passing through the screen device 23.

The improved device may be of any required material or of any required size or capacity.

Having thus described the invention, what is claimed as new is:

1. A device of the class described comprising a receptacle having a conical diaphragm provided with a discharge and a valve seat surrounding the discharge, a valve engaging said seat and having an upwardly directed stem, an annular screen member supported at its outer edge upon the diaphragm and spaced above the valve seat,'a central supextending over. the central support an connected thereto and to the diaphragm.

2. A device of the class described comprising a receptacle having a transverse diaphragm. provided with a discharge and a valve seat surrounding the discharge, a valve engaging said seat and having an upwardly directed stem, a supporting ring engaging sald dlaphragm, an annular screen member supported at its outer edge by said ring and spaced above the valve seat, a central support connected to the inner edge of the screen and provided with a guide aperture to receive the valve stem, and a stay bar extending over the central support and connected thereto and to the ring.

3. A device of the class described comprising a receptacle having a discharge and a valve seat surrounding the discharge, a valve engaging said seat and having an upwardly directed' stem, an annular screen member supported at its outer edge by the receptacle and spaced above the valve seat, and a central support connected to the inner edge of the screen and providedwith aguide aperture to receive the valve stem.

I

5. A device of the class described comprising a receptacle having a transverse diaphragm provided with a discharge and a valve seat surrounding the discharge, a valve engaging said seat and having an upwardly directed stem, an annular screen member supported at its outer edge upon the dia- ,phragm and spaced above the valve seat, a central support connected to the inner edge of the screen and provided with a guide and through which the valve stem is slidably disposed.
